Safety
Warning!
Dangerous Electrical Voltage!
Before Commencing the Installation
●
Disconnect the power supply of the device
●
Ensure that devices cannot be accidentally restarted
●
Verify isolation from the supply
●
Earth and short circuit the device
●
Cover or enclose any adjacent live components
●
Only suitably qualified personnel in accordance with 
EN 50110-1/-2 (VDE 0105 Part 100) may work on this 
device/system
●
Before installation and before touching the device ensure 
that you are free of electrostatic charge
●
The functional earth (FE, PES) must be connected to the 
protective earth (PE) or the potential equalization. The 
system installer is responsible for implementing this 
connection
●
Connecting cables and signal lines should be installed so 
that inductive or capacitive interference does not impair 
the automation functions
●
Install automation devices and related operating elements 
in such a way that they are well protected against 
unintentional operation
●
Suitable safety hardware and software measures should 
be implemented for the I/O interface so that an open 
circuit on the signal side does not result in undefined 
states in the automation devices
●
Ensure a reliable electrical isolation of the extra-low 
voltage of the 24V supply. Only use power supply units 
complying with IEC 60364-4-41 (VDE 0100 Part 410) or 
HD384.4.41 S2
●
Deviations of the input voltage from the rated value must 
not exceed the tolerance limits given in the specifications, 
otherwise this may cause malfunction and dangerous 
operation
●
Emergency stop devices complying with IEC/EN 60204-1 
must be effective in all operating modes of the automation 
devices. Unlatching the emergency-stop devices must not 
cause a restart
●
Devices that are designed for mounting in housings or 
control cabinets must only be operated and controlled after 
they have been installed and with the housing closed. 
Desktop or portable units must only be operated and 
controlled in enclosed housings
●
Measures should be taken to ensure the proper restart of 
programs interrupted after a voltage dip or failure. This 
should not cause dangerous operating states even for a 
short time. If necessary, emergency-stop devices should 
be implemented
●
Wherever faults in the automation system may cause 
injury or material damage, external measures must be 
implemented to ensure a safe operating state in the event 
of a fault or malfunction (for example, by means of 
separate limit switches, mechanical interlocks, and so on)
●
Depending on their degree of protection, adjustable 
frequency drives may contain live bright metal parts, 
moving or rotating components, or hot surfaces during and 
immediately after operation
●
Removal of the required covers, improper installation, or 
incorrect operation of motor or adjustable frequency drive 
may cause the failure of the device and may lead to 
serious injury or damage
●
The applicable national accident prevention and safety 
regulations apply to all work carried out on live adjustable 
frequency drives
●
The electrical installation must be carried out in 
accordance with the relevant regulations (for example, 
with regard to cable cross sections, fuses, PE)
●
Transport, installation, commissioning, and maintenance 
work must be carried out only by qualified personnel 
(IEC 60364, HD 384 and national occupational safety 
regulations)
●
Installations containing adjustable frequency drives must 
be provided with additional monitoring and protective 
devices in accordance with the applicable safety 
regulations. Modifications to the adjustable frequency 
drives using the operating software are permitted
●
All covers and doors must be kept closed during operation
●
To reduce hazards for people or equipment, the user must 
include in the machine design measures that restrict the 
consequences of a malfunction or failure of the drive 
(increased motor speed or sudden standstill of motor). 
These measures include:
●
Other independent devices for monitoring safety-related 
variables (speed, travel, end positions, and so on)
●
Electrical or non-electrical system-wide measures 
(electrical or mechanical interlocks)
●
Never touch live parts or cable connections of the 
adjustable frequency drive after it has been 
disconnected from the power supply. Due to the charge 
in the capacitors, these parts may still be live after 
disconnection. Fit appropriate warning signs
